Quick propagation method of aquatic landscape plant lythrum salicaria

Abstract

The invention provides a quick propagation method of an aquatic landscape plant lythrum salicaria. 150 ppm of ABT rooting powder solution containing 0.1-0.2 mg of cytokinin is used as a rooting induction solution, and the quick propagation method specifically comprises the following steps that a plurality of branches of lythrum salicaria which is pure in variety and free of diseases and pests arecollected as female parent; the tip parts of lythrum salicaria shoots are selected and cut to obtain cutting slips, each cutting slip is 5-6 cm long, one third of leaves at the base are removed, eachcutting slip has to have two or more eyes, and the cutting slips are washed clean for standby; the tail ends of the cutting slips are treated for 10-20 minutes with the rooting induction solution; thecutting slips are subjected to cuttage under the conditions that the plant spacing is 5 cm, the row spacing is 10 cm and the cuttage depth is 1-2 cm, and the temperature and humidity are managed andcontrolled after cuttage; the cutting slips can root 7-10 days after cuttage, can have well-developed root systems 20 days after cuttage and can be subjected to out-planting more than one month aftercuttage, and transplanting is conducted. By means of the quick cuttage propagation method, rooting of the lythrum salicaria can be quickly and efficiently facilitated, the propagation period can be shortened, the time cost of the propagation can be effectively saved, and a great number of mature lythrum salicaria plants can be provided for the market.

Description

technical field [0001] The invention belongs to the technical field of plant propagation and cultivation, and relates to a rapid propagation method of the aquatic landscape plant quincetrum, in particular to a rapid propagation method of the cuttage of the quince. Background technique [0002] Lythrum salicaria (Lythrum salicaria L.) is a perennial herb belonging to the family Lythraceae, also known as water branch willow, water willow, and lotus. Elegant and elegant, with a long flowering period. In the garden landscape configuration, it can be planted in clusters by rivers, pools or garden roads as a flower border, can be planted in the open field, potted or cut flowers. In recent years, there are more and more water bodies and larger areas in gardens and green spaces, and the application of aquatic plants is becoming more and more abundant. As an excellent aquatic landscape plant, the market demand for its mature plants is gradually increasing , and at the same time, Tri...

Problems solved by technology

The operation of ramet propagation is complicated, and the reproduction effect is poor, so it is generally not used for the batch propagation of Trigonum chinensis; the spring sowing of sowing and propagation is carried out in the wetland environment from March to April, and the propagation cycle is generally long, which cannot realize the rapid propagation of Trigonum trigonum; traditional Cutting propagation generally directly cuts off the branches of Trichosanthes for cuttings, resulting in low rooting rate, slow rooting, and low plant survival rate
